 STP 0 degrees and 101 KPa SATP 25 degrees and 100 KPa Pressure is.... force per unit area What are four physical properties of gases? Always fill their containers Are highly compressible Diffuse Temperature effects either the volume or the pressure of a gas The pressure exerted by air Atmospheric pressure (1 atm) ________ effects either the volume or pressure of a gas Temperature Gases increase in volume and pressure when _______ Heated At sea level, average atmospheric pressure is about.... 101 KPa What does STP stand for? Standard temperature and pressure What does SATP stand for? Standard ambient temperature and pressure What is Boyle's Law? as the pressure on a gas increases, the volume of the gas decreases, other variables such as temperature and amount of gas remain constant. How can we write out Boyle's Law? V1P1= V2P2 Convert 20 degrees celcius into Kelvin 293 K Convert 300K into degrees celcius 27 degrees celsius What are the temperatures in K of STP and SATP? STP= 273 K SATP=298 K French physicist Jacques Charles determined the relationship between the ______ and ______ of a gas temperature and volume What number do you add to convert degrees celsius to kelvin? 273!! What does the Charles law state? The volume (V) increases proportionally as the temperature (T) increases What is the formula used in the Charles Law? V1 = V2 -- -- T1 = T2 True or false Temperature must be in Kelvin in the Charles Law? True What do you call the Charles and Boyles Law when put together? The combined gas law What is the formula for the combined gas law? p1v1 = p2v2 ------------ T1 T2 Molar mass is in... g/mol How do we calculate the molar mass? 1. Write the correct chemical formula 2.Find the atomic molar mass 3. Add together What formula do we use when we need to find the relationship of amount in moles, mass and molar mass? n= m -- M What is the molar volume of a gas at SATP? 24.8 L/Mol What is the molar volume of a gas at STP? 22.4 L/Mol Why is it easier to work with volume instead of the mass of a gas? It is much more convenient because it is more precise, since gases have such small amoounts of mass. what is the formula for molar volume? n= v --- V
